StarTools ($) or Astro Pixel Processor ($$) are native on Macs. They are alternatives to PixInsight ($$$).
Nebulosity ($) is a good all around package that does everything, but is a bit dated and the GUI is clunky.
PHD2 (free) is the default guider app of the universe. A debt is owed to Craig Stark by all astrophotographers for his pioneering work and choosing to release it to the world.
KStars and EKOS (both free) are fantastic (camera control and mount control). Integrates with SkySafari ($) and PHD2, but includes Its own guider and planetarium/scope control too. I use them all with a Raspberri Pi to wirelessly run everything on my remote MacBook Pro via Stellarmate ($) app. Runs through my house wifi. Can also be run in the field with a laptop or iPad. ASI Air ($$) is an interesting platform and deserves consideration, although not sure what the compatibility is with Mac OS or IOS.
An older version of Photoshop ($) is handy to have for post processing, but not required if you have one of the more advanced stackers. The new version is only by subscription ($$$).
Those are the ones I have experience with and knowledge of. Good Luck!
